Hi preetism110,
To start, if you are not scoring near your Goal Score, then you should consider rescheduling your Exam (the fee is $50, but you have to make the choice to reschedule at least 7 full days before your Test Date; if it's too late, then you are 'stuck' with this Test Date).
Beyond that issue, before I can offer you the specific advice that you’re looking for, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
